JACQUARD-CARD-REPEATING MACHINE.

PECIFIQATION forming part of Letters Patent No. 438,508, dated October14, 1890.

Application filed October 31, 1889. Serial No. 328,798. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM P. UHLINGER, a citizen of the UnitedStat-es, and a resident of Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new and usefulImprovements in Card- Repeating Machines; and I do declare the followingto be afull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

Figure 1 of the drawings is arepresentation of a side view of themachine. Fig. 2 is a front View. side of the machine. Fig. tis asectional view of the upper portion of the machine. Fig. 5 is a sectionshowing the main cams. Fig. 6 is an enlarged detail view, partly insection, and a side view of one of the adj usting-pins and its adjustiveparts for adjusting the blank for the action of the punchers. Fig. 7 isan enlarged detail plan view of the Jacquard cylinder herein employed.Fig. 8 is an enlarged detail perspective view of the adjustable supportfor taking up the slack of the feed-chain t. Fig. 9 is an enlargeddetail perspective View disclosing more clearly the connection betweenthe abutment-keys E and 6 Fig. 10 is a detailed sectional view showingmore fully the retention in an upright position of the hooked ends ofthe wires 6 by the guiderods V.

This invention has relation to machines for providing series of Jacquardcards which shall be in the disposition of their perforations exactduplicates, card for card, of the series of pattern Jacquard cards whichfor the time au tomatically regulate the operation of the Fig. 3 is aview of the oppositeits upper portion a boxing B, and in front lateralguides at for the vertically-reciprocating die-carriage 0, above whichis located the punch-head D. In the boxing B is located the system ofhorizontal abutment keys, which are arranged in tiers, as shown, and inthe rear portion of said boxing are the adjusting-wires, which arerespectively connected to said keys and are automatically operated bythe pattern-card to retract the abutment-keys from over the puncherswhich are not required to perforate the blank card, as hereinafterdescribed.

The keys E are longitudinally movable, and are placed in bearings band 6of the boxing B.

B is a slide-rack which has reciprocating motion in rear -of saidboxing. The front or abutment ends of the keysE extend through thebearings e of the oblique partitions A of the boxing, which is providedin front with overhanging steps or shoulders a, arranged in series oneabove another, each step above projecting a little beyond the next belowit, as shown, so that a transverse shoulder or step is provided aboveeach row of vertical punches in the punch-head. The keys are providedwith stops or collars a which limit their forward movement, and withsprings e", which hold them normally in forward or projected position,their abutment ends in this position extending beyond the front facetsor' risers of the partition A a distance equal to the breadth of theshoulders at overthe same. The slide-rack B is provided with horizontalguides d, moving in bearings d of the boxing B, these guides carryingthe vertical transverse rack-frame, which is formed with a verticalseries of transverse bars or catches c, which are usually slightlyinclined downward from the front to their rear or engagement edges. Inthe construction illustrated one of these transverse catch-bars islocated above each tier of keys just over the rear ends of said keys,which are each provided with an operating-wire having a rearupward-turned hook end 8'. Normally these hook ends lie between thecatch-bars of the rack B; but when said rack is moved forward and thekeys are raised in rear by their adjusting rods or wires f the hook endsof said keys will be elevated sufficiently to engage the catch-bars ofthe rack B when the latter is moved to the rear, and consequentlythekeys will be drawn backward, so that their front or abutment ends willnot project beyond the partition A of the boxing B. When so drawn backthe keys will offer no obstruction to the upward movement of thepunchers, which will therefore be free to rise to the shoulder of saidpartition above their upper ends. Said shoulder is located usually ahalf-inch or more above the lower or abutment surfaces of the ends 6 ofsaid keys, in order that there will be sufficient vertical distance topermit the punchers to vary in length in each row, so that they will notoperate exactly together in passing through the card in thedie-carriage, but will act in a successive manner, thereby easing theoperation of the machine.

The action of the keys is controlled by the pattern-cards P as they passintermittently over the Jacquard cylinder E, which is located below theoverhanging rear end of the boxing B of the frame. This cylinder is ofthe usual rectangular form, havingthe full number of perforations fextending through it from side to side and from top to bottom, saidperforations being equal in number on each side to all the perforationswhich a J aequard card of the size employed can carry. This is also thenumber of the keys, of the adjusting-wires attached to said keys, and ofthe punchers in the front of the machine. The Jacquard cylinder moves upand down intermittently, its journals being seated in bearings of thearms C, which are pivoted at c", said arms carrying the steady-heads 0,their slide-stems, and the springs 0" thereof. The pivotal points 0 arelocated about even with the lower surface B of the overhanging rearportion of the boxing B, so that when the Jacquard cylinder is broughtup against the same it will work squarely against it, its position beingprecisely ascertained, so that its perforations are exactly under thelower ends of the respective adjusting series of the keys, said endsprojecting below the surface B a distance sufficient for the amount ofthrow required to raise the hook ends of the keys to engage thecatch-bars of the rack B. Pivoted to the side of the boxing B is thedouble or reversible turning-hook F, which is adjustable, being providedwith the adjusting-springs, of which one serves when in engagementtohold the turning-hook in position to turn the cylinder as the latterreciprocates in one direction, while the other will operate when inengagement to turn it in the opposite direction. The Jacquard cylinder Fis reciprocated intermittently bymeans of crank-pins on the transverseshaft S, to which are connected the pitman-rods d, which are adjustablein the yokes d which are carried on the journal-pins d of the arms 0'.The shaft S is provided with a sprocketwheel 8, which is operated by achain t',con nected to a sprocket-wheel s on the lower front transverseshaft S", which is provided with a large gear-wheel G", engaging apinion .G' of the shaft S in rear of and parallel to the shaft S". Theshaft 8' is turned by the driving-shaft S by means of the engaginggear-wheels G and G.

In front the frame is provided with the projecting arms A, upon whichare the adj ustable bearings a, which are provided usually withjournal-seats a and a of different elevation, to accommodatefeed-cylinders of different size. These arms A are located at the sidesof the frame and extend rearward, as indicated at 1 in the lateralrecessed or boxed sides of said frame to their rear bearings at a. Theinner portions of said arms also carry adjustable bearings a, providedwith journalseats a' and a at different heights.

F" indicates the front and rear feed-cylinders, which are pivoted in thebearings a", and which are provided with the sprocketwheels 8 s, whichare connected by the chain 15. The front feed-cylinder is provided witha pinion g on its shaft, which engages a pinion g on a parallel shaft Sbelow it, the latter shaft carrying a sprocket-wheel sflwhich isconnected to the sprocket-wheel s of the adjustable intermittent wheel Iby the chain 25. The wheel I is provided on the side opposite to thesprocket-wheel s with the crossslot cam I, having its four sections 1"provided with the concave outer bearings i, and it is operated byengagement with the intermittent circle and pin-cam J on the shaft S.This cam governs and regulates the intermittent rotation of thepattern-cylinder F and the feed-cylinders F F, the rotation of the shaftS being continuous.

On the shaft S are the laterally-arranged eccentrics H, which engage theyoke-arms, which extend vertically upward and are pivoted to strong pinsh in bearings 72/ of the diecarriage O. This carriage is thereforereciprocated by the shaft S through said eccentrics and yoke-arms, whichbeing paired and located laterally and immediately below thedie-carriage operate to give it a perfectly steady and true movementnotwithstanding the varying manner in which the punchers operate withthe die-earriage. The pattern card on the Jacquard cylinder F isconstantly being changed as the successive pattern-cards reach saidcylinder, and therefore different sets of punchers are constantly beingset to punch the blank cards Z, and as the distribution of theperforations of the pattern-card P is usually uneven and sometimesextremely so more punchers are usually set for action on one side of thepunch-head than the other, and therefore it is important to provide fora steady and true movement of the die-carriage on which the blank cardis carried, and into the die-perforations of which the operating ends ofthe punchers descend in cutting the card. The punchers L are verticalsteel rods, which are seated in the guide-shelves in the punchhead D.They are arranged in transverse rows, one row back of another, and aboveeach punch the abutment end of its key projects ITO . tion by thepattern-card of the Jacquard cylinder F do not enter the die-plate belowthe guide-plate. Between the die-plate C and the guide-plate C is thefeed-slot or interspace m, which is provided with the lacinggrooves m,extending from front to rear and designed to permit the lacings of theseries of cards Z to move freely through the slot m as the cards are fedto position by the intermittent movement of the feed-cylinders F.

The distance between the feed-cylinders F is regulated by adjusting thebearings on the arms A" A so that those cards Z which extend from one ofsaid cylinders to the other will be exactly suflicient and in properposition to bring the blank tobe acted upon by the punchers to place inthe feed-slot m, where it is precisely adjusted by the reciprocatingset-pins 1;, which have conical ends 12' and extend through perforatedseats or ways '0 in the guide-plate 0 into perforations o of thedie-plate 0 A rock-shaft S back of the punch-head D is provided withlateral arms K, which are provided with pins engaging slot-bearings 7cof the set-pins o, and said shaft is operated by the grooved cam K' onthe shaft S through its engagement with the pitman K which is providedwith a pin engaging the camgroove. After the card Z to be punched hascome to position in the feed-slot the re-entrant portion of thecam-groove rocks the shaft S to cause the set-pins to descend, and theirconical ends entering adjusting-perforations z, which are provided inthe blank cards Z before feeding them to the machine, bring the cards totrue and exact position under the punchers. The rack-slide B of theboxing B is reciprocated by means of a similar groove-cam K on the shaftS", a pitman K having at its lower end a yoke carrying a pin 70 whichengages the cam-groove of said cam and operates the crank-shaft S, whichis provided with the lateral sets of arms 71. and n in angular relationto each other, said arms being respectively pivoted to the pitman andconnected by links to lateral guide-rods of the rack B.

The hook ends e of the keys E are suspended in normal position betweenthe catchbars of the rack B by means of the adjusting-wires f, whichhave stops Z near their lower ends, which engage the horizontalbearingsZ of the boxing B; The keys, as I preferto construct them, consist ofthe cylindrical slide-rods or keys proper and the Wires a having thefront loops e connected to eyes e in the rear ends of said slide-rods.The slide-rods are seated in bearings in. the oblique partition A and inthe vertical partition in rear thereof, and vertical removableguide-rods V, arranged in series andextending through the transverse topbar B of the boxing B, serve to afford bearings at the sides of theloops 6, so that the wires e are prevented from turning, and their hookends 6'' are held in proper upturned position for engagement with thecatch-bars of the rack.

The frame of the machine is usually provided with rearward-extendingarms R, having supporting-cylinders R, over-which the series ofpattern-cards is drawn by the J acquard cylinder F, said cards, afterpassing the Jacquard cylinder, returning along the inclined track rodsor rails R" on the inside of said arms.

One of the arms a" of the frame is provided with an adjustable support Vfor taking up the slack of the feed-chain t.

The cards, as they are punched, are designed to be numbered insuccession or in sets of two, three, four, 850., in accordance with thecharacter of the work and the number of shuttles employed under thepattern. This is important for the guidance of the weaver and to avoiderror in replacing a card in the pattern series.

The numbering device \V may be of ordinaryreciprocatin g character,having the usual numbering-wheels and carrying-pawls and a vibratorypawl operating shaft having a crank-arm w, slottedto receive theactuatingpin w of the reciprocating portion W. The numbering device islocated on the punch head over the extension-plate V, which projectsfrom the die-plate, and it is operated by the cam W on the shaft S, saidcam engaging the pin of a pitman W" which is pivoted at its upper end tothe crank-arm o of a short shaft W which is provided witha yoke orconnection W engaging the reciprocating portion W and pivoted to an armor arms on the opposite side of said shaft. In this manner the weight ofthe pitman is utilized in raising the yoke and allowing thereaches itslowest position, the cylinder F turns, feeding the next card Z to thedie-slot. The rack B moves forward a little after the commencement ofthe descent of the'die-carriage to disengage the adj ustment-wires f andallow the abutment ends of the keys which had retracted to project intothe punch-head. As the Jacquard cylinder moves away from theadjusting-wires, it is turned one-quarter round, and being then held bythe steadyheads of the arms A" presents the next patterncard uppermost.As the diecarriage moves upward, the slide-rack, having been moved tothe rear and having retracted certain keys by its engagement with thehook ends of their wires, is held stationary, as also are the set-pins,until the punching is effected between the plates of the die-carriage.As the rack-slide B reaches its forward position, releasing the keyswhich had been held back by its catch-bars, the Jacquard cylinder risesand carries upward certain of the adj ustingwires which are over theimperforate portions of the pattern-card P to raise said wires. Then therack-slide, returning upon its backward movement, engages the hook endsof the key-wires by means of its transverse catclrbars and dra ws thekeys back into their seats in the oblique partition A, so that theirends will not project and the corresponding punchers will not beoperated to produce perforations in the card Z. The retracted rack-slideand retracted keys are held in this position until the punching iseffected by the rise of the diecarriage and the engagement of theprotruding ends of the keys which have not been retracted with theircorresponding punchers. hen the rack-slide B is in its forward position,all the hook ends of the key-wires project in rear beyond itscatch-bars; but when the rack-slide is moving to its rear position itscatch-bars pass over said hook ends and do not engage the same unlessthey are raised by the adj usting-wires pressed upward by theimperforate portions of the patterncard. The time of the intermittentcam feeding the cards Z takes place as the die-carriage reaches itslowest position.
